Best Place To Buy Tips?

I have ruined a bunch of tips over the last few years and was wondering if anyone knew of the best place to buy a bunch of tips. I want to buy a bunch of duplicates of the most often used ones as well as replace some that look bad or that the disposal ate . I don't want to spend a lot and they can add up fast!

I just ordered some from CountryKitchen. They were $1.30 each for the (00 and 0). The only thing that I don't like is that their shipping fee starts off at $7.95 and goes up. But that's pretty much anywhere. This past summer I ordered from Wilton's website and the shipping was the same.
